OSSGR Section 10: System Interfaces

ABSTRACT: This document describes, by traffic function, the additional analog trunk interface requirements placed on the operator services system
beyond those given in GR-540. The required signaling and pulsing characteristics for each additional trunk type are also provided.

This document details the information contained in the SS7 Transaction Capabilities Application Part (TCAP) messages exchanged
between an operator services system Core System and LIDB or billing validation database. This includes generic requirements for each
query and response message and associated message elements for core system-to-LIDB communications.

Issue 7 includes:

TCAP IDs for two (2) newly defined standard elements, which are retrievable from LIDB via GetData, and other wireless and
IP-based protocols (e.g., LDAP) via protocol conversion: Extended Name (EN) String and EN Presentation Indicator. The Extended Name may
be retrieved for the CLASS Calling Name Delivery feature where longer names could be supported in signaling and CPE, as well as for
various GetData and IP-based applications.
